A lot of my friends have been telling me about this site, so I decided to take a look. You all seem pretty cool and willing to help out, so here it goes. I also had my car stole, a couple of months ago, and have just finally started to piece it all back together. My problem is the thieves tried to take my engine, and disconnected a lot of things. They seemed to have "stolen (I guess)" the O2 sensor's harness that leads to the ECU; because of this, my engine does not operate correctly (It revs only to 3000rpm's, maxes out at 45mph, and reaks of fuel when started). I believe this problem is because of the O2 sensor and is hopefully not that they blew my motor, bent rods, etc. I just need to know which pins to wire the O2 sensor to, on my ECU so I can manually fix the problem without buying a new harness. I have only one O2 sensor (93 Civic DX) that is located right before my CAT.

Any help would be appreciated!!!

 

wires o2 sensor diagram for a obd1 harness. correct me if im wrong guys.

Run O2 Sensor signal (white) To D14
Run O2 Sensor signal Ground (green) to D22 (or any good Ground)
Run O2 Sensor Heater Circuit Control (black) to A6
Run the other black heater circuit power wire to (A25) or any good switched +12VDC source.

i dont think the o2 sensor affecting the car to revs only to 3000 or max out at 45mph.

 

something else is wrong. The O2 would not put the car into limp mode like that.

 

How do I know which pins are which???????

 

I need to know which black is which black?????????????? How can I tell by viewing the O2 sensor?
